My invention relates to an improvement in bookmarkers.

In the past, many forms of bookmarking devices have been in use.primarily as temporary markers to indicate a page Which is later to beeasily found. Many markers, such as markers used in card index files,are provided with protruding edges Which are adapted to receive a numberor some other indicating media, such markers being either permanent orof a type which may be secured to a page or card so that it may beremoved at a. later date.

In the past, markers for books which are adapted to indicate a pagewhich may be referred l5 to, have been secured Within the book by someclamping device closely associated with the binding of the book.

An object of my invention. is to provide a bookmarker which is adaptedto t over a. page to be marked and leave a portion of the markerprotruding beyond the edge of the page so that reference may be readilyhad to a desired page.

A further object of my invention is to provide a bookma-rker which isadapted to be placed over a page so that one strip forming the markerwill be on, each side of the page.

A further object of my invention is to provide a bookmarker which hasportions thereof extending beyond the edge of a page which is to bemarked, these portions being secured to the holding portion of themarker in varying positions relative to its length, so that theprotruding edges will not overlap one another.

A further object of my invention is to provide a bockmarker havingportions thereof extending beyond the edge of the page which is to bemarked, these portions being of varying lengths and secured to theholding portion of the marker so that the holding portion will bepositioned at varying distances from the binding of the book to Whichseveral markers have been applied.

A still further object of my invention is to provide a bockmarker whichis telescopic so that one given marker may be adjusted to fit pages ofdifferent sizes.

A still further obj ect is to provide a bookmarker which is adapted tohold a sheet of reference paper which may be of Water-proof or Washablepaper so that the memoranda placed on the sheet may be erased or changedfrom time to time, these memoranda sheets being removably secured to thebookmarker which is positioned on a given page to be marked.

A still further object of my invention is to provide a bookmarker whichis adapted to hold, on

the end thereof which protrudes beyond the edge of the page to bemarked, a reversible indicating medium, which indicating medium isadapted to have varying marks on the opposite sides thereof.

I provide two relatively thin strips 2 preferably made of celluloid orthick cellophane, which strips are secured together at both ends 4thereof by any suitable cement, in which case they will assume theposition shown in Figs. 1, 10, 16 and 17, or which may be folded overupon themselves at the ends thereof as shown in Figs. 21 and 22. Betweenthe two end portions 4, the strips 2 are separable so that they may beplaced over a page 6 which is to be marked.

Strips 8 of the same material are laterally secured to each of thestrips 2 by a suitable cement. These strips 8 extend outwardly from thestrips 2, and the outer ends thereof I6 are cemented together so thatwhen the strips 2 are placed over a page 6, the page will also be inposition between the strips 8 with the portion I0 thereof extending outpast the edge of the page. As shown in Fig. 5, the outer end I0 of thestrips 8 may be out away as at I2, so that the reference indicator I4may be slipped over the end I 0. This reference indicator I4 may be madeof any suitable material, for example in varying colors, and havingvarying reference numbers or letters on either or both sides thereof.

The strips 8, as shown in Fig. 1, may be modified slightly to providethe end portion particularly disclosed in Figs. 6, 7, 8 and 9. In thiscase the strip 8 is folded over upon itself and is cemented together inclose proximity to the slot I6 which is formed in the outer end thereofand is adapted to receive the indicating medium I8.

As shown in Figs. 1 and 2, I have cemented, or otherwise secured, arelatively small piece of washable or waterproof paper 2U, to both ofthe strips 2 (as shown particularly in Fig. 2), but it will beunderstood that this piece of Washable paper may or may not be used ason the form of marker which is described above.

In Fig. 10, I have shown a modiiied form of marker which issubstantially the same in its general construction, but which isprovided with strips 22 placed over the upper portion of the page 24 tobe marked, and to which are cemented the laterally extending strips 26which are provided with a protruding portion 28 on the outer edgethereof. Similar strips 30 are adapted to extend from the lower portionof the page 24 upwardly and are slidably secured to the strips 22 by thestraps 32 which are secured to the strips 3D and extend around thestrips 22. These straps 32 may be pushed in an upward direction untilthe upper edges of the straps 32 are abutting against the lateralextending strip 26. The strips 3D may be pulled downwardly until thelower edge of the straps 32 abut against the stops 34 which are cementedto the lower ends of the strips 22. It will be understood that thestrips 22 and 3l) are telescopically connected, as shown moreparticularly in Fig. 13, and are adapted to t one size page while themarker is in its contracted posi tion and to t varying larger sizes ofpages as the telescopic strips are stretched outwardly as shown indotted lines in Figs. 10 and 13.

In Fig. 16, I have shown an ordinary page 36 of a book on which fiveseparate markers have been placed. These markers are made in varyingshapes, as illustrated, so that the several markers may be placed on onepage of the book and yet the protruding lateral marking strips 3B willnot overlap and may be readily seen and selected by the person wishingto refer to the particular page which is marked. It will be understoodthat these several markers shown in Fig. 16 will be preferably made of atransparent material, so that printed matter on the page 36 may be readwithout removing the several reference markers.

Markers shown in Fig. 16 are shown all applied to one page, but it willbe understood that these markers of varying configuration may be used ondifferent pages, so that the indicating means protruding beyond the edgeof the pages will not overlap, and also so that the strips 40, which areplaced one on each side oi a page being marked, will not all assume aposition of the same relative distance from the binding of the book.These markers shown in Fig. 16 are, generally speaking, the same as themarkers shown in Figs. 1 and 2, although the memoranda sheet 20 has beenleft off of the top of the markers so that more than one marker may beapplied to one page without interfering in any way with the othermarkers applied to that same page.

By means of the varying configuration of these markers, a great manymarkers may be used in one volume without damaging the binding byexpanding the covers too great a distance.

In the form which I have shown in Fig. 17, I have illustrated atelescoping form of marker similar to that shown in Fig. 10, which isprovided with two laterally extending strips 42 which are secured to theholding strip 44. This form of marker is adapted to hold a sheet ofwaterproof or washable paper 46 in position over a page 43 which is tobe marked. The memoranda sheet 46 is held in position by the straps 5Dwhich are cemented to the under side of the memoranda sheet 46 and formloops through which the later ally protruding strips 42 may pass to holdthe memoranda sheet in position. These memo randa sheets 46 are adaptedto be readily removable from the marker shown in Fig. 17 by merelysliding the memoranda sheet off over the ends of the laterally extendingstrips 42.

While I have shown in Fig. 19, two of these memoranda sheets 46positioned on opposite sides of a page 48 by being slipped into positionover the laterally extending strips 42 on opposite sides of the page, itwill be understood that the marker disclosed in Figs. 17, 13, 19, and 20need not necessarily be provided with laterally extending strips 42 onboth sides of the page 48 being marked.

This form of telescoping marker shown in Fig. i7 differs from the formshown in Fig. 10 in that the holding strips extend from the top of thepage 46 downwardly and are positioned over the strips 43 which extendupwardly from the bottom of the page At the bottom edges of the strips44, I provide binding straps 45 .i

which are cemented to the strips 44, and hold the strips 43 in positionat the bottom of the strip 44. At the upper end of the strips 43, Iprovide stops 4l which are cemented to the strips 43 and are adapted toslide with the strips 43 between the strips 44. After the strips 43 havebeen pulled through their entire length and the markers expanded to t tothe largest possible page to which it may be applied, the stops 41 abutagainst the straps 45 and preclude the marker from being enlarged more.This form of telescoping marker may be pushed into a smaller space thanthe form disclosed in Fig. l0, because the straps are mounted at thebottom end of the marker and will remain in a xed position relative tothe laterally extending strips 42, whereas in Fig. 10, the straps 32slide on the strips 22 and abut against the laterally extending strip 26when the marker is in its collapsed position.

ISI)

Figs. 21 and 22 disclose a strip 8 which has been folded over uponitself, this being particularly adapted to be used at the lower end ofthe marker so that no portion of the marker will extend beyond thebottom edge of a page, and thereby make it impossible or difficult toplace a book in a standing position upon a book-shelf after one or moreof my marking devices have been applied to the book.

It will be understood that the upper ends of the marker may be made inthis form as well as the lower end, in which event one strip t will befolded over upon itself at two points, and the ends of the strip will besecured together at some convenient place by any suitable means.

While I have shown several slightly modified forms which my bookmarkermay take, it will be understood that other minor changes may becomeapparent from time to time as these modied forms of markers are appliedto Varying types of books, card-digests and the like, to which they maybe applied to afford easy reference to any selected passage, citation,or quotation.
